Here two photos of an Aluminum Head I picked up a few years ago. Soon, I hope to install it on the IND-7(236.6) which is installed in my WC 1/2 ton Military 4x4. it will save me weight over the 41' Spifire head I have on it now, and it has been shaved down for some higher compression. I have bought a Chrysler steel head gasket as they say to use steel instead of cooper.
